However, the information collection unit 11 may acquire the event information X of the device 20 stored in the control device 22 manually by a user via a storage medium such as a DVD-ROM, for example.
The event information X generated during the operation of the apparatus 20 includes information on an alarm generated by each device 21 of the apparatus 20, information on the operation state of each device 21, and information on the operation of each device 21 (see fig. 4). The information on the operation of each apparatus 21 includes information on the operation of each apparatus 21 and information on the adjustment operation of each apparatus 21. The event information X also includes information related to a system alarm generated by the operation information analysis device 10.
The information on the alarm generated by each device 21 includes information on a failure or abnormality of each device 21, an alarm issued when the processing amount P of each device 21 exceeds a control management value, and the like. In the present embodiment, the case of issuing an alarm is defined as "generation", and the case of stopping an alarm is defined as "recovery".
In the present embodiment, of the start/stop operations (start instruction or stop instruction, or open instruction or close instruction) are performed for each of the devices 21 is defined as "ON" and another of the start/stop operations are defined as "OFF" for each of the devices 21.

The information analysis unit 12 acquires the event information X from the information collection unit 11, and generates and accumulates a database Y of a plurality of index values for each period divided based on the operating state of the device 20. Here, in the present embodiment, the change in the operating state of the device 20 refers to a change in the operating load of the generator 21g and a change in the type of fuel used in the equipment 21 (for example, a gas turbine, a steam turbine, or the like) for driving the generator 21 g.
The change in the operating load of the generator 21g varies according to the state of the generator 21g during the starting process, the rated operation process, the partial load operation process, the minimum load operation process, the stopping process, and the stopping of the generator 21 g. The starting process is, for example, a process in which the generator 21g is operated at an output of 35% or less of the rated load until a predetermined time elapses without output variation. The rated operation process is a process in which the generator 21g is operated at an output of 90% or more of the rated load, for example. The partial load operation process is a process in which the generator 21g is operated at an output of 40% or more and less than 90% of the rated load, for example. The minimum load operation process is, for example, a process in which the generator 21g is operated at an output of less than 40% of the rated load. The stop process is a process in which the generator 21g is operated at an output of 5% or more and less than 35% of the rated load and until the operation of the generator 21g is stopped. The stop is a state in which the operation of the generator 21g is stopped.
